18. An Adobe Commerce Developer is tasked with writing an importer for a custom entity. After the work is complete and deployed, they start receiving complaints from their client that the importer does not work and fails every time they use it.

The developer realizes that the client is importing a file which does not match the format required for the importer to process correctly.

What two features would the developer add to this importer to prevent this? (Choose two.)

Set up an example file and inject it into the ExampleFileProvider .

Set up a try/catch in the importer to display a warning the file is not in the correct format.

Set up validation by implementing a validateRow method in their importer.

Set $needColumnCheck = true; and add column names to the $validColumnNames class properties.

19. A message queue currently has queue/consumer-wait-for-messages set to true, which allows the consumer process to run until a message is inserted into the queue. A piece of functionality is driven by data stored in the model.MagentoVariable\Modelvariable and this value is only loaded once during the consumer run. If the variable is updated we want the consumer to restart so that the new value is loaded into memory without having to reload the variable on each message consumed.

The Adobe Commerce developer has created an after plugin on the Magentovariablevariable::save() function.

How would the developer use the plugin to trigger the consumer restart?

Set the global cache key trigger_consumer_resart to 1.

Call the function MagentoFrameWorkMessageQueueConstomers triggerRest art Interface: trigger () .

Call the function MagentoFrameworkMessageQueuePoisonPillPoisoninterface::put() .

This is the content of the module's etc/webapi.xml file:

The new code has been deployed to production and the merchant is using https: //merchant.domain.com/swagger to review the new endpoint, but it is not visible in swagger.

What would be a reason for this?

Since the new endpoint is not anonymous, the merchant needs to enter a valid integration token in swagger in order to see the new method.

The webapi.xml file should be moved into the etc/webapi_rest/webapi.xml file.

The @return annotation is missing in the MyVendorBlogApiPost Repositoryinterfacec

31. An Adobe Commerce Developer wishes to add an action to a pre-existing route, but does not wish to interfere with the functionality of the actions from the original route.

What must the developer do to ensure that their action works without any side effects in the original module?

In the route declaration, use the before or after parameters to load their module in before or after the original module.

Inject the new action into the standard router constructor's Sactionlist parameter.

Add the action into to the Controllers/front.name/ in My_Module. Magento will automatically detect and use it.

32. An Adobe Commerce Developer is tasked with creating a custom module which implements a new product type. Upon completion, they find that any quantity information they enter against the product does not get saved, and reverts back to 0.

How would they go about correcting this?

In the modules ete/product_types.xml file, set the isQty-"true" property on their product type declaration node.

Create a new root category in the admin and then select it when creating the website.

Create a new root category in the admin and then select it when creating the store.

36. An Adobe Commerce developer is developing a class that is executed in both the frontend and crontab areas. When executed in the frontend MagntoCustomerModelsession::getCu5tonteria() is called but when executed in the crontab this section of code is skipped.

Keeping performance and best practices in mind, what would be the best approach to achieve this?

Inject the MagentoCustomerModelSessionProxy class in the constructor of their class and call the getCustomer id function wherever required in the class.

Declare MagentoCustomerModelSession in the constructor dependency of their class and declare a proxy in the di.xml. Then call the getCustomerid function wherever required in the class.

Declare MagentoCustomerModel.session in the constructor of their class dependency and call the getCustomrid() function wherever required.

37. When building a custom page we need to get a collection of data. To determine how many items are in this collection, the Adobe Commerce developer uses $collection->count() . This sometimes is slow and causes some delay.

What is the reason?

The collection is loaded first and then the number of items in the collection are returned.

Before the collection is loaded, the framework performs left joins for all related attributes are added to the query.

The framework internally uses SELECT count(-) and that is slower than loading the collection.

38. The developer is required to convert a modules database scripts from old install/upgrade setup files to a data patches format and does not want to apply database changes that were already done by install/upgrade scripts.

The current module version is 1.5A

What would be the recommended solution to skip changes that were already applied via old format (install/upgrade scripts)?

This is not possible. A module cannot implement both data patch and install scripts.

Inside apply() method, check for module version and run the code it version is less than 134,

Implement PatchVersioninterface and return 1.5.4 on the getversion() method.

39. An Adobe Commerce Developer is tasked with creating a module which generates a sitemap by cron. While writing the module, they realize they will need to use environment emulation to ensure the data is generated from a frontend perspective. They notice that the Emulation: :startEnvironmentEmulation() method accepts a $force parameter.

Why would this be set to true?

To reset the environment emulation configuration to the current store.

To emulate a new environment while already emulating a different one.

To ignore any exceptions which may otherwise get thrown during emulation.

40. There is the task to create a custom product attribute that controls the display of a message below the product title on the cart page, in order to identify products that might be delivered late.

The new EAV attribute is.deloyed has been created as aBooleanand is working correctly in the admin panel and product page.

41. An Adobe Commerce Developer is tasked with creating a custom form which submits its data to a (rontend controller. They have decided to create an action and have implemented themagntoFrameworkAppAction|HttpPostInterface class, but are not seeing the data being persisted in the database, and an error message is being shown on the frontend after submission.

After debugging and ensuring that The data persistence logic is correct, what may be cause and solution to this?

Magento does not allow POST requests to a frontend controller, therefore, the submission functionality will need to be rewritten as an API endpoint.

The developer forgot to implement a ValidatePostData() method in their action. They should implement this method: all non-validated POST data gets stripped out of the request and an error is thrown.

Form key validation runs on all non-AJAX POST requests, the developer needs to add the form_key to their requests.

42. A client wants to change the look and behavior of the products thumbnails in the products grid on the admin panel.

Which code would be added to the module's view/adminhtml/ui_component/product_listing.xmlfile?

Using the integration access token as Bearer

44. When using the traditional Magento frontend, an Adobe Commerce developer is tasked to create a before plugin every time that the totals information loads on the cart page summary.

Considering performance, where would the di .xml be added?

etc/di.wni

etc/frontend/di.xml

etc/webapi_rest/di.xml

45. A product has some stock and quantity in the Sources panel in its edit view m the admin:

But when trying to add this product to the cart on the frontend. the following error is displayed:

The total quantity of this product in all active quotes has reached its available stock.

The number of reservations for this product has already reached its available stock.

46. An Adobe Commerce developer adds a new extension attribute to add an array of values to the invoices that are fetched through the APIs.

After a while, their technical manager reviews their work and notices something wrong with the extension_attributes.xml file that the developer created in their module: extension_attributes for="MagentoSalesHotelOrderInvoiceRepository"> attribute code"my_code" type=string]’’> </extension_attribute>

What is the problem with this xml snippet?

The extension attribute references the repository instead of the interface it implements (MagentoSalesApiinvoiceRepositoryinteface

The type is wrong, string[] should be replaced with array.

The extension attribute references the wrong interface it should have referenced the MagentoSalesAPiInvoiceinterface.

47. Create a data patch copying those exceptions to their original destinations like vendor/magento/ framework /except Ion/ to replace original files.

48. An Adobe Commerce developer is being tasked with creating a new cron job to run a method that has already been written.

• Products: 300k

• Customers: 700k

• Customer groups: 106

• Orders :1600k

• Invoices: 500k

• Creditmemos: 50k

• Websites: 15

• Stores: 45

What is a probable cause for this?

The combination of the number of orders, customers, invoices and creditmemos is too big. This leads to a huge amount of values being stored in the customer grid index which is too large to be processed at a normal speed.

The combination of the number of products, customer groups and websites is too big. This leads to a huge amount of values being stored in the price index which is too large to be processed at a normal speed.

The combination of the number of products, categories and stores is too big. This leads to a huge amount of values being stored in the flat catalog indexes which are too large to be processed at a normal speed.

50. An Adobe Commerce developer is being tasked with storing additional data for products added to the cart in the quote. A newcolumn should be added to the Quote_item table to store the value-Following best practices, how would the developer extend the database to accomplish this?
